To all whom it mar/y concern:

Be it known that L'Gnonen DINKEL, a citizen ot' the United States,residing at Jersey City, county of Hudson, State ofvNew Jersey, haveinvented certain new and useful Improvements in Apparatus for ObtainingLime Sucrate, of which the following is a specification.

My invention relates to apparatus through the instrumentality of whichthe sugar constituent of a solution of beet molasses and water may becombined with lime to form tricalsic sucrate. It has heretofore beenproposed to add lime to the solution by distributing the lime in a finepowder over such portion of the surface of the solution as is exposed inthe containing vessel and at the same time agitate the solution;further, to

introduce the lime by blowing it into a powder and distributing it overthe surface of a moving stream of the solution. In practice both of thedescribed methods. have been found objectionable, owing to the fact thatneither method provides means for effecting a uniform distribution of adefinite quantity of lime to a definite quantity of the solution or forpreventing heating and forming of the solution due to the chemicalreactions, gases, &c., which result when an indefinite quantity of limeis introduced into a large quantity of solution.

In practice I have found that if a definite quantity of lime isuniformly distributed to a definite quantity of solution within a giventime the amount of lime required will be materially reduced and theheating and foaming of the solution cut down to a very considerableextent, if not entirely prevented. The apparatus described, therefore,maybe said to have for its purpose, first, to decrease the amount oflime used; second, to provide means whereby an intimate and uniformmixture of the lime and molasses solution may be brought about; third,to provide means for measuring the quantity of lime introduced per unitof solution andtime, and, fourth, to provide means for preventingfoaming and heating.

The accompanying drawings will serve to illustrate my invention,- inwhichor other materials in the slots. however, may be formed withparallel sides.

Figure 1 is a vertical section. Fig. 2 is a transverse section and planon the line :20 m of Fig. 1. Fig. 3 is a transverse section and plan ontheline'yy of Fig. 1. Fig. 4isaverticalsection of the lower portion ofthe apparatus, showing the inclosing vessel provided with coolingapparatus and connected to an external cooling apparatus shown at therightin elevation. tributing-arms and partial section of thedistributing-plate, taken on the line W W of Fig. 2. Fig 6 is a verticaltransverse section of one of the distributing-arms, taken on the line VV of Fig. 5. Fig. 7 is a top View of the distributing-cone.

Similar numerals indicate like parts.

In the drawings, 5 indicates the inclosing vessel, which may be of anyrequired shape,

preferably of greater height than width. Lo cated on the top of thevessel is a feed-hopper 6, through which the lime is introduced in theform of a fine powder. The feed-hopper communicates at its bottom with ahorizontal chamber 7, in which is located a feedscrew 8, adapted to berotated by means of the pulley 9. The horizontal chamber 7 communicates,through a delivery-chute 10, with a fixed conical distrib uting-chamber11,which I prefer to have open at the top.

Arranged transversely of the inclosing vessel is a distributing-plate12, through which is formed the concentric and equally-spaced slots 13.These slots are wider at the bottom 14: than at the top and arepreferably so made to prevent the permanent lodgment of lime The slots,

Arranged vertically in the inclosing vessel is a shaft 15, on the upperend of-which is a beveled gear 16, in mesh'with a beveled gear 17 onshaft 18, on which is located the loose pulley 19 and the fixed pulley20.

Mounted on the shaft 15 over the distribut- I V ing-plate 12 and securedin position thereon by means of an adjustable collar 21, so as to berotated with the shaft, is the distributingspider 22. This spiderconsistsof the central hub 23 and the radial arms 24. The arms 2+tarearranged equidistant and are triangularin section, as shown in Fig.6. Igive zoo Fig. 5 isaside view of one ofthe dis them this section so as toprevent lodgment of the lime on the top of the arms. Depending from thearms 24 and located in the slots 13 are the pins 25, corresponding innumber along the arms with the number of concentric slots.

Situated over the spider and carried by the radial arms 24 is adistributing cone 26. Formed on the surface of this cone and arrangedequidistant are the projecting ribs 27. The base of the cone has formedin it the V- shaped slots 28, which rest over the radial arms 24 of thedistributing-spider 22.

Mounted on the shaft 15 within the conical distributing-chamber 11 arethe agitators 29, each having two or more blades.

Mounted upon the shaft 15 below the distributing-plate 12 is adistributing-wheel 30. One or more wheels may be employed. Thisdistributing-wheel consists of a hub 31, secured to shaft 15, from whichproject a series of radial equally-spaced spokes 32, secured at theirouter ends to the rim 33. Arranged between the hub 31 and the rim 33 arewires 34, preferably so disposed that two wires will be located, one onthe top of the wheel and one on the bottom of the wheel, as illustratedin Fig. 1. Pairs of wires are arranged equidistant around the wheel. Ido not limit myself to the precise construction of distributing-wheelshown and described, as it may be otherwise formed. That shown, however,I find suitable to the purpose.

Arranged across the bottom of the inclosing vessel 5 is a plate 35,having the centrally-disposed opening 36. Carried by this plate is a.pipe or tube of large diameter, 37, which is rigidly secured within theinclosing vessel by means of the braces 38. Situated on the top of thepipe 37 is a shaped plate 39.

' This plate I prefer to give substantially the shape shown-that is,approximately con- -ical-with the baseof the cone horizontal and theapex carried downward and flared outward to form the discharge-opening40. The upper surface 41 of this plate I prefer to make smooth, so asnot to interfere with the passage of the molasses solution over it. Thelower surface of the plate is provided with offsets 42 and ribs 43, bymeans of which it may be secured to the pipe 37 and which serve tostrengthen the plate.

It will be observed from the construction described that the space belowthe plate 39 is divided into two chambers-i. 6., the chamber 44, which Iterm the exhaustchamber, and the chamber 45, which I term thedelivery-chamber. Connected to the exhaustchamber at the bottom oftheinclosing vessel is an eduction-pipe 46, and connected to thedelivery-chamber at four points is an induction-pipe 47. Situatedbetween these pipes, so as to draw from one and deliver into the other,there is shown, Fig. 4, a pump 48. Any suit-able pump may be employed.

In the modified construction shown in Fig. 4 the plate 35, correspondingto 35, is shown as situated below the cone-shaped plate 39, and locatedbetween the plates 35 35, which are perforated to receive them, are thetubes 49. In this figure the interior of the tubes 49 form a part of thedeliverychamber 45. The space surrounding the pipes 49 and includedbetween one wall of the containing vessel 5, the pipe 37, and the plates35 35 I term the cooling-chamber. This chamber is connected through thepipes 50 50 with anysuitable source of cooling fluid, which bycirculating in the cooling-chamber around the pipes 49 acts to cool thesolution flowing through them. In this figure I have also shown meansfor cooling the solution external to the containing vessel, and toaccomplish this the eduction and induction pipes 46 47 are surrounded bypipes 51, connected through the pipes 52 52 with any suitable source ofcooling fluid. I do not limit myself in any wise to the apparatus shownin Fig. 4 for cooling the solution within the inclosing vessel orexternal to the vessel, as very many other devices may be used toaccomplish the same result. The cooling devices may, as shown in Fig. 1,be omitted.

The general operation of my device is as follows: Assuming the sugarsolution to be flowing over the surface of the plate 39 as a thin streamof uniform thickness and rapidity offlow, the lime, in a fine state ofdivision, is introduced into the hopper 6, from which it falls into thehorizontal chamber 7 and under the action of the feed-screw 8 is fedthrough the chute 10 into the conical chamber 11 and from thence on tothe rotating cone 26, to be distributed over the surface of thedistributing-plate 12. The rotation of the spider 22 and the movement ofthe pins 25 in the slots 13 in the distributing-plate serve to cause thelime to pass through the slots as a series of fine streams, which infalling strike the wires 34 of the distributing-wheel 30, which servesto effect a union of such streams or otherwise break up the integrity ofsuch streams of falling lime. The lime-cloud formed, as it may betermed, is deposited upon a thin body of the solution, (indicated bydotted lines, Fig. 1,) flowing from the delivery-chamber 45 over thecone-shaped plate 39 and into the eXhaust-chamber44. It will be observedfrom the drawings, Fig. 1, that the level of the solution in theexhaust-chamber is lower than that in the delivery-chamber. This is dueto the action of the pump 48. I prefer that the action of the pump shallbe such that but a thin stream or body of solution shall be constantlymoved over the upper surface of the cone-shaped plate 39 and that themouth or discharge-opening40 of the coneshaped plate 39 shall be belowthe level of the solution in the delivery-chamber. This, however, is notessential, but I find that it materially aids in preventing foaming ofthe solution at this point.

It will be readily understood from the description that the amount oflime which will ICC pass through the distributing-plate 39 will dependupon the number and size of the slots 13 in such plate and the speed ofrotation of the spider 22, and that by varying the size of slots 13 andspeed of rotation of the spider more or less lime may be caused to passthrough this plate within a given period of time and that such deviceserves to measure the amount of lime delivered within a given unit oftime; further, that if a definite thickness and rapidity of movement ofstream of lution over the shaped plate 39 is maintained a definiteamount of lime will be deposited upon a definite quantity of solutionwithin a definite time.

The action of the cooling arrangement need not be described, as it iswell understood.

1 wish it understood thatI do not limit my-, self to the particularconstruction of all of the parts of the apparatus as described or to thecollective use of all of such parts, as various changes may be made inor some of such parts omitted-as, for instance, the mechanism fordistributing the finely-divided material may be different from "thatdescribed, or portions of said mechanismas, for instance, thedistributing-conemay be omitted without in any wise departing from theintent of my invention.
